To all whom/ it may concern: I

trip-lever. Fig. 11 is a detail side elevation of pivoted trip E andadjacent parts operating in connection therewith in positions assumedwhen a current impulse is passed through the magnet, the releasedposition of parts being indicatedin dotted lines. Fig. 1 2 is asimilarview showing parts in readjusted positions ready for the next currentimpulse.

The invention relates to punching-registers especially adapted for usein connection with fire-alarm and police telegraph systems; and itconsists, mainly, in the novel construction and combinations of parts,a'shereinafter set forth. Y v

The object of the.invention is mainly to provide, in connection withsuitable escapement devices andv gearing, in connection with amainspring-wheel and an electromagnet, a punch of simple and efficientcharacter having a positive return movement, such being an improvementupon my Patent No. 633,982, hearing date October 3,1899.

In the accompanying drawings, illustrating the invention, the letter Adesignates the incasement, having a pedestal portion or base B, in whichis provided an electromagnet 0', having an armature-lever D, the upperend of which engages intermittently the pivoted trip E, which isprovided with a stop-arine and a lever-arm a, these arms beingonopposite sides of the punch-operating shaft F,

which is provided with a stop-arm]; and a cam c. 'This shaft is alsoprovided with a pinion d, which engages through intermediate gearing ona shaft G the teeth of the main spring-wheel H.

I is the feed-wheel on theend ofthe shaft e, andfis a toothed wheel onsaid shaft en-- gaging by pawl g and rachet g a loose pinion h on thisshaft, said pinion h engaging the sector-geart' of the spring-operatedlever I. The lateral roller-stud j on the lever I engages the cam o ofthe punch-operating shaft F. The toothed wheel f of the shaft e engagesa pinion of the shaft k, which is provided with an escapement-wheel K,whose teeth are engaged by the pallets of the escapement Z, carried by arock-shaft L, provided with a weight L. i i N represents a latch orcatch leverpivote to the incasement and having a beveled endportion'N,terminating at its lower extrem .ity'in an inwardly-ofiset shoulder N 3This lever has also a depending extension at its outer extremityterminating in an outwardlyoffset shoulder N and has a link connection Nwith the trip E. This trip is provided with a laterally-extending lug nof .wedge form whichirests upon the upper end of the armature-lever whenin raised position. The armature-lever is laterally notched at its upperextremity, which is of wedge form, the lug n being received iii-thisnotched portion when thetrip falls, its fall being l-imitedbythe lowerwall of said notch. The armature-lever has a lateral lug 0, providedwith'a bev- When thecurrent impulse attracts the armature, the leverthereof is actuated to re .lease the lever N, which has previously beenheld in raised position'with its shoulder N in engagement with the lug0, and which falls. This leaves the armature-lever free to move in thereverse direction under the influence of its'spring, which releases thetrip E, which falls andis immediately returned to raised positionthrough the rotation of arm I), act:

ing upon lever-arm a, which releases the train of gearand allows thepunch-shaft to bev ro tated one full revolution, after which thefeed-shaft continues to turn during the upward movement of thesector-gear i, driven downward by the action of the cam upon thepunch-shaft. A feed of the tape will thus always be effected between theoperations of the punch to perforate the same.

The movement of the armature-lever under the action of its spring islimited by the engagement of the lug 0 thereof with the beveled endportion of the lever N. As the trip is raised it raises the lever Nthrough its link connection therewith, and as the leverNrises it pushesthe armature-lever back a short distance by the engagement of lug 0 withbeveled portion N until the shoulder N catches upon the lug 0. At thesame time the upper end of the armature-lever is brought underneath thelug n and the parts are ready to be again operated.

M represents the support for the reel of tape, and m a tangentialledge-guide secured to the wall of the incasement and slotted for theserrated edge of the feed-wheel.

P represents the positive return -punch, which is provided with theslotted head-plate p. The slot 3 of this head-plate is of sufficientwidth to take the eccentric r of the punching-shaft F and isisometrically arranged with reference to the axis of the punch. The slothas parallel upper and lower walls and is covered in front by means of afaceplate t, which is secured to the head by screws. A flange upon theoperating-shaft covers in the slot of the punch-head at the rear.

The punch-stem c passes through a perforation u in the guide-block R,which is secured to the side wall of the casing. This guide-block isprovided with perforations or recesses z for the reception of guide andholding studs 10, secured to the case-wall and designed to fix properlythe position of the block when secured by the screw S. When this screwis removed, the punch-block, punch, and die-plate can all be removedfrom the casing for repair or other purpose.

U is the die-plate, which .is provided with a front upturned flange 1,through perforations in which screws 2 2 pass into the block R to securethe plate in position. The floor of the plate is held away from thebottom of the block R by the narrow raboet 3, which projects downwardfrom the front of the block, this rabbet being of sufficient depth toprovide between the bottom of the block and the fioor of the plate apassage for the tape indicated at 4. The plate rests on the top of thetube 5, which is secured to the casing and forms a passage for thepunchings as well as a seat for the plate. The die-plate isprovided withthe die-perforation 6, which is beveled in such manner that it can beeasily sharpened and will at the same time afford free way to thepunchings. The eccentric r on the end of the shaft F is provided with aflange 7 at its back to facilitate oiling and to keep the slot of thepunch-head closed.

When the trip is loosed, allowing the gearing to rotate thepunch-operating shaft, the eccentric by one revolution presses the punchthrough the tape and then positively returns the punch' to normalposition, in this manner avoiding all chance of error through thesticking of the punch in the tape or by reason of thickened oil or othertemporary obstruction. The movement of the punch is made instantaneous,not only to secure rapid work, but also because the movement of the tapeis continuous, and it is therefore important to have the motion of thepunch also entirely positive and certain.
